Using the sonochemical method, nano-plates of a 3D Zn(II) metal−organic framework (MOF) were synthesized and characterized using FT-IR spectroscopy and PXRD. The effect of various irradiation durations and concentrations of reagents was investigated to obtain uniform morphologies. Increasing the irradiation time along with decreasing the reagent concentration led to the production the particles with a uniform nano-plate morphology. Also, the sensing potential of these nano-plates to detect nitroaromatic analytes such as nitrophenol, 2,4-dinitrophenol, and TNP was explored. The nano Zn MOF was highly selective and sensitive in the detection of nitroaromatic derivatives. The quenching percentages of fluorescence emissions for a 2ppb concentration of nitrophenol, 2,4-dinitrophenol, and TNP were 11%, 42%, and 89%, respectively. According to the results, the MOF has the strongest detection limit for TNP.
